    In PHP versions before 5.0.0 you must use <A
HREF="function.ocinumcols.html"
><B
CLASS="function"
>ocinumcols()</B
></A
> instead.
    This name still can be used, it was left as alias of
    <B
CLASS="function"
>oci_num_fields()</B
> for downwards compatability.
    This, however, is deprecated and not recommended.
